One of the most popular Halo gametypes returns in Halo: Reach – the "humans vs. zombies" mode called Infection. In this mode, one player is chosen at random to become a "zombie." Anyone then killed by the zombie joins the ranks of the undead! Each Spartan Zombie is painted in "zombie green" and comes with an Energy Sword. Spartan Human has a blue & gold paint scheme and comes with a DMR.
